Maskey

I have got a 3 door Mk4 escort estate. I want to put the RS dropskirts on the front and rear bumpers. The front is not a problem. However, when it comes to the rear bumper, the dropskirt from an rs turbo is to short and the dropskirt off the orion is to long. I have seen this done before in mag features. Does anybody do a fibreglass copy to fit the estate or am i just going to have to cut the orion one down.
Any help would be greatly appreciated as this is now holding up my sprayer.
